The image display device 200 may be mounted in a vehicle in a fixedmanner, and may be connected to the mobile terminal 100 through a fixedline or wirelessly to receive at least one of an image and a voice fromthe mobile terminal. Also, the image display device 200 may output atleast one of the image and voice which has been received from the mobileterminal.

The image display device 200 may receive a user input and transmit thereceived input to the mobile terminal 100. For example, when the userapplies a touch input through a touch screen provided to the imagedisplay device 200, a position of a point to which the touch input hasbeen applied in the image is recognized, the information regarding therecognized position may be transmitted to the mobile terminal 100.

Then, the mobile terminal 100 may determine that a touch event hasoccurred at the point at which the touch input has been applied, and mayperform an operation corresponding to the generated touch event. Namely,the user may control the operation of the mobile terminal 100 by using atouch screen, a hard key, or the like provided to the image displaydevice 200.

In an embodiment of the image transmission system, the user may executea road guide application (or dialing, a phone book, an e-mail, a movingimage play application, and the like) installed in the mobile terminal100 and the mobile terminal transmits an executed image of the roadguide application to the image display device 200 so that the executedimage of the road guide application can be displayed on the imagedisplay device 200.

The user can view the executed image of the road guide application on alarge screen of the image display device 200 in the place of a smallscreen of the mobile terminal 100. Also, the user can listen to a roadguide voice through a speaker provided to the vehicle in the place of aspeaker of the mobile terminal 100.

Also, when the user selects a menu related to the road guide by using atouch screen or a hard key provided to the image display device 200, anoperation with respect to the corresponding menu can be performed on themobile terminal 100. The mobile terminal may transmit the results ofperforming the operation with respect to the corresponding menu to theimage display device 200 so that the image display device 200 can outputthe same.

The server application of the mobile terminal 100 may capture an imageof the screen of the mobile terminal regardless of an application typeof the mobile terminal 100 and transmit the captured image to the clientapplication of the image display device 200. Also, the serverapplication controls the operation of the mobile terminal 100 on thebasis of information regarding an event generated in the image displaydevice 200 from the client application.

For example, the image display device 200 may remotely control themobile terminal 100 according to a VNC (Virtual Network Computing)scheme using an RFB (Remote Frame Buffer) protocol providing a remoteaccess to a graphic user interface. According to the VNC scheme, whilethe mobile terminal 100 is transferring screen update to the imagedisplay device, an input event generated by the image display device 200is transmitted to the mobile terminal 100.

Also, the mobile terminal 100 may transit a voice to the image displaydevice 200, a headset, a hands free, or the like, according to, forexample, an A2DP (Advanced Audio Distribution Profile) defining soundquality of an audio (stereo or mono) signal or output which can bestreamed from a first device to a second device, an HSP (HeadSetProfile) regarding a Bluetooth headset, an HFP (HandsFree Profile)applied to a vehicle hands free kit, or the like.

The wireless communication unit 110 may include one or more componentsallowing the mobile terminal 100 and a wireless communication system toperform radio communication or the mobile terminal 100 and a network inwhich the mobile terminal 100 is located to perform radio communication.For example, the wireless communication unit 110 may include a broadcastreceiving module 111, a mobile communication module 112, a wirelessInternet module 113, a short-range communication module 114, and alocation information module 115.

The broadcast receiving module 111 receives broadcast signals and/orbroadcast associated information from an external broadcast managementserver (or other network entity) via a broadcast channel. The broadcastchannel may include a satellite channel and/or a terrestrial channel.The broadcast management server may be a server that generates andtransmits a broadcast signal and/or broadcast associated information ora server that receives a previously generated broadcast signal and/orbroadcast associated information and transmits the same to a terminal.The broadcast signal may include a TV broadcast signal, a radiobroadcast signal, a data broadcast signal, and the like. Also, thebroadcast signal may further include a broadcast signal combined with aTV or radio broadcast signal.

The broadcast associated information may also be provided via a mobilecommunication network and, in this case, the broadcast associatedinformation may be received by the mobile communication module 112. Thebroadcast signal may exist in various forms. For example, broadcastsignal may exist in the form of an electronic program guide (EPG) ofdigital multimedia broadcasting (DMB), electronic service guide (ESG) ofdigital moving image broadcast-handheld (DVB-H), and the like.

The broadcast receiving module 111 may be configured to receive signalsbroadcast by using various types of broadcast systems.

Such radio signals may includea voice call signal, a moving image call signal or various types of dataaccording to text and/or multimedia message transmission and/orreception.

The wireless Internet module 113 supports wireless Internet or othernetwork access for the mobile terminal. This module may be internally orexternally coupled to the terminal. Here, as the wireless Internettechnique, a wireless local area network (WLAN), Wi-Fi, wirelessbroadband (WiBro), world interoperability for microwave access (WiMAX),high speed downlink packet access (HSDPA), and the like, may be used.

The short-range communication module 114 is a module for supportingshort range communications. Some examples of short-range communicationtechnology include Bluetooth™, Radio Frequency IDentification (RFID),Infrared Data Association (IrDA), Ultra-WideBand (UWB), ZigBee™,Wireless LAN, and the like.

The location information module 115 is a module for checking oracquiring a location (or position) of the mobile terminal. For example,the location information module 115 may be embodied by using a GPS(Global Positioning System) module that receives location informationfrom a plurality of satellites. Here, the location information mayinclude coordinate information represented by latitude and longitudevalues. For example, the GPS module may measure an accurate time anddistance from three or more satellites, and accurately calculate acurrent location of the mobile terminal according to trigonometry basedon the measured time and distances. A method of acquiring distance andtime information from three satellites and performing error correctionwith a single satellite may be used. In particular, the GPS module mayacquire an accurate time together with three-dimensional speedinformation as well as the location of the latitude, longitude andaltitude values from the location information received from thesatellites. As the location information module 115, a Wi-Fi positionsystem and/or hybrid positioning system may be used.

The A/V input unit 120 is configured to receive an audio or moving imagesignal. The A/V input unit 120 may include a camera 121 (or other imagecapture device) and a microphone 122 (or other sound pick-up device).The camera 121 processes image data of still pictures or moving imageobtained by an image capture device in a moving image capturing mode oran image capturing mode. The processed image frames may be displayed ona display unit 151 (or other visual output device).

The image frames processed by the camera 121 may be stored in the memory160 (or other storage medium) or transmitted via the wirelesscommunication unit 110. Two or more cameras 121 may be providedaccording to the configuration of the mobile terminal.

The microphone 122 may receive sounds (audible data) via a microphone(or the like) in a phone call mode, a recording mode, a voicerecognition mode, and the like, and can process such sounds into audiodata. The processed audio (voice) data may be converted for output intoa format transmittable to a mobile communication base station (or othernetwork entity) via the mobile communication module 112 in case of thephone call mode. The microphone 122 may implement various types of noisecanceling (or suppression) algorithms to cancel (or suppress) noise orinterference generated in the course of receiving and transmitting audiosignals.

The user input unit 130 (or other user input device) may generate keyinput data from commands entered by a user to control various operationsof the mobile terminal. The user input unit 130 allows the user to entervarious types of information, and may include a keypad, a dome switch, atouch pad (e.g., a touch sensitive member that detects changes inresistance, pressure, capacitance, etc. due to being contacted) a jogwheel, a jog switch, and the like. In particular, when the touch pad isoverlaid on the display unit 151 in a layered manner, the display unit151 may be called a touch screen.

The sensing unit 140 (or other detection device) detects a currentstatus (or state) of the mobile terminal 100 such as an opened or closedstate of the mobile terminal 100, a location of the mobile terminal 100,the presence or absence of user contact with the mobile terminal 100(i.e., touch inputs), the orientation of the mobile terminal 100, anacceleration or deceleration movement and direction of the mobileterminal 100, etc., and generates commands or signals for controllingthe operation of the mobile terminal 100. For example, when the mobileterminal 100 is implemented as a slide type mobile phone, the sensingunit 140 may sense whether the slide phone is opened or closed. Inaddition, the sensing unit 140 can detect whether or not the powersupply unit 190 supplies power or whether or not the interface unit 170is coupled with an external device.

The interface unit 170 (or other connection device) serves as aninterface by which at least one external device may be connected withthe mobile communication terminal 100. For example, the external devicesmay include wired or wireless headset ports, an external power supply(or battery charger) ports, wired or wireless data ports, memory cardports, ports for connecting a device having an identification module,audio input/output (I/O) ports, moving image I/O ports, earphone ports,or the like.

In addition, the device having theidentification module (referred to as the ‘identifying device’,hereinafter) may take the form of a smart card. Accordingly, theidentifying device may be connected with the terminal 100 via a port orother connection device. The interface unit 170 may be used to receiveinputs (e.g., data, information, power, etc.) from an external deviceand transfer the received inputs to one or more elements within themobile communication terminal 100 or may be used to transfer databetween the mobile communication terminal and an external device.

The output unit 150 is configured to provide outputs in a visual,audible, and/or tactile manner (e.g., audio signal, moving image signal,alarm signal, vibration signal, etc.). The output unit 150 may includethe display unit 151, an audio output module 152, an alarm unit 153, ahaptic module 154, and the like.

The display unit 151 may display information processed in the mobileterminal 100. For example, when the mobile terminal 100 is in a phonecall mode, the display unit 151 may display a User Interface (UI) or aGraphic User Interface (GUI) associated with a call or othercommunication (such as text messaging, multimedia file downloading,etc.). When the mobile terminal 100 is in a moving image call mode orimage capturing mode, the display unit 151 may display a captured imageand/or received image, a UI or GUI that shows moving images or imagesand functions related thereto, and the like.

The display unit 151 may include at least one of a Liquid CrystalDisplay (LCD), a Thin Film Transistor-LCD (TFT-LCD), an Organic LightEmitting Diode (OLED) display, a flexible display, a three-dimensional(3D) display, or the like. The mobile terminal 100 may include two ormore display units (or other display device) according to its particulardesired embodiment. For example, the mobile terminal may include both anexternal display unit (not shown) and an internal display unit (notshown).

Meanwhile, when the display unit 151 and the touch pad are overlaid in alayered manner to form a touch screen, the display unit 151 may functionas both an input device and an output device. The touch sensor may havethe form of, for example, a touch film, a touch sheet, a touch pad, andthe like.

Also, the touch sensor may be configured to convert the pressure appliedto a particular portion of the display unit 151 or a change incapacitance generated at a particular portion of the display unit 151into an electrical input signal. The touch sensor may be configured todetect a touch input pressure as well as a touch input position and atouch input area. When there is a touch input with respect to the touchsensor, the corresponding signal(s) are sent to a touch controller (notshown). The touch controller processes the signal(s) and transmitscorresponding data to the controller 180. Accordingly, the controller180 can recognize a touched region of the display unit 151.

The proximity sensor 141 may be may be disposed within the mobileterminal covered by the touch screen or near the touch screen. Theproximity sensor 141 refers to a sensor for detecting the presence orabsence of an object that accesses a certain detect surface or an objectthat exists nearby by using the force of electromagnetism or infraredrays without a mechanical contact. Thus, the proximity sensor 141 has alonger life span compared with a contact type sensor, and the proximitysensor 141 can be utilized for various purposes.

The proximity sensor 141 may include, for example, a transmission typephoto sensor, a direct reflection type photo sensor, a mirror-reflectiontype photo sensor, an RF oscillation type proximity sensor, acapacitance type proximity sensor, a magnetic proximity sensor, aninfrared proximity sensor. When the touch screen is an electrostatictype touch screen, an approach of the pointer is detected based on achange in an electric field according to the approach of the pointer. Inthis case, the touch screen (touch sensor) may be classified as aproximity sensor.

In the following description, for the sake of brevity, recognition ofthe pointer positioned to be close to the touch screen without beingcontacted will be called a ‘proximity touch’, while recognition ofactual contacting of the pointer on the touch screen will be called a‘contact touch’. In this case, when the pointer is in the state of theproximity touch, proximity touch means that the pointer is positioned tocorrespond vertically to the touch screen.

The proximity sensor 141 detects a proximity touch and a proximity touchpattern (e.g., a proximity touch distance, a proximity touch speed, aproximity touch time, a proximity touch position, a proximity touchmovement state, or the like), and information corresponding to thedetected proximity touch operation and the proximity touch pattern canbe outputted to the touch screen.

The audio output module 152 may output audio data received from thewireless communication unit 110 or stored in the memory 160 in a callsignal reception mode, a call mode, a record mode, a voice recognitionmode, a broadcast reception mode, and the like. Also, the audio outputmodule 152 may provide audible outputs related to a particular function(e.g., a call signal reception sound, a message reception sound, etc.)performed in the mobile terminal 100. The audio output module 152 mayinclude a receiver, a speaker, a buzzer, etc.

The alarm unit 153 outputs a signal for informing about an occurrence ofan event of the mobile terminal 100. Events generated in the mobileterminal may include call signal reception, message reception, keysignal inputs, and the like. In addition to moving image or audiosignals, the alarm unit 153 may output signals in a different manner,for example, to inform about an occurrence of an event. For example, thealarm unit 153 may output a signal in the form of vibration. When a callsignal is received or a message is received, the alarm unit 153 mayvibrate the mobile terminal through a vibration device. Or, when a keysignal is inputted, the alarm unit 153 may vibrate the mobile terminal100 through a vibration device as a feedback with respect to the keysignal input. Through the vibration, the user may recognize theoccurrence of an event. A signal for notifying about the occurrence ofan event may be output to the display unit 151 or to the voice outputmodule 152.

The haptic module 154 generates various tactile effects the user mayfeel. A typical example of the tactile effects generated by the hapticmodule 154 is vibration. The strength and pattern of the haptic module154 can be controlled. For example, different vibrations may be combinedto be outputted or sequentially outputted.

Besides vibration, the haptic module 154 may generate various othertactile effects such as an effect by stimulation such as a pinarrangement vertically moving with respect to a contact skin, a sprayforce or suction force of air through a jet orifice or a suctionopening, a contact on the skin, a contact of an electrode, electrostaticforce, etc., an effect by reproducing the sense of cold and warmth usingan element that can absorb or generate heat.

The haptic module 154 may be implemented to allow the user to feel atactile effect through a muscle sensation such as fingers or arm of theuser, as well as transferring the tactile effect through a directcontact. Two or more haptic modules 154 may be provided according to theconfiguration of the mobile terminal 100. The haptic module 154 may beprovided to a place which is frequently in contact with the user. Forexample, the haptic module 154 may be provided to a steering wheel, agearshift, a lever, a seat, and the like.

The memory 160 may store software programs used for the processing andcontrolling operations performed by the controller 180, or maytemporarily store data (e.g., a map data, phonebook, messages, stillimages, moving image, etc.) that are inputted or outputted.

Known as the machine learning algorithm includes an SVM (Support VectorMachine), an ANN (Artificial Neutral Network), or the like.

The SVM refers to a map learning method using a statisticsclassification and regression analysis. SVM applies a technique of alinear classification to a nonlinear classification problem by using akernel trick.

The SVM refers to one of learning models having the most excellentrecognition performance among the numerous schemes known so far. Thereason for the SVM to exhibit the excellent recognition performance isbecause SVM includes a scheme for obtaining a high recognitionperformance with respect to non-learning data.

The SVM is uses a linear threshold element and configures a 2-classpattern recognizer. A parameter of a linear threshold element is learnedon the basis of the reference called a margin maximization from atraining sample.

The ANN is a mathematical model aiming at expressing the somecharacteristics of a brain function by a computer simulation. ANN isalso called a neural network, and when ANN is strictly discriminatedfrom biology or a brain science, ‘artificial’ is attached in front ofthe acronym.

The ANN generally refers to a model having a problem solving capabilityby changing a coupling strength of synapses through learning of anartificial neuron (node) forming a network by coupling the synapses. Ina narrow sense, the ANN may indicate a multi-layer perception using anerror back-propagation method, but the ANN is not limited thereto.

The ANN includes supervised learning optimized for a problem byinputting a supervising signal (correct answer) and unsupervisedlearning which does not require a supervising signal. When there is aclear solution, the supervised learning is used, and the unsupervisedlearning is used for data clustering. Resultantly, in order to reduceevery dimension, a good reply may be obtained with a relatively smallamount of calculation with respect to a problem which cannot be linearlyseparated, by multi-dimensional data such as an image, statistics, orthe like. Thus, ANN is applied in various fields, such as a patternrecognition, data mining, or the like.
